If you have ever tried to remove the nub left when the core pops out, your tip can be at center height, but as soon as it touches the nub, it can drop up to an inch because of the flex. I think this is one of the reasons that we can get so much chatter some times, especially in harder woods. When the tip starts cutting, it goes down below the center line, which is not good for scrapers.

I agree, and add that sometimes it's necessary to adjust the speed as you get closer to the center. With the majority of the tool beyond the rest, vibration can be factor. Small speed adjustments can help to minimize this.
